Sam Lowes was unable to maximise his time on the Gresini Aprilia during the final test of 2016, with the British rider still feeling the effects of his spill at Valencia.
Lowes, who makes the step up to the MotoGP premier class on the RS-GP machine, managed 50 laps over the three-day test, which was affected by variable weather conditions.
The British rider managed his best lap in 1m 42.312s compared to team-mate Aleix Espargaro, who managed a lap in 1m 39.675s to end the combined MotoGP/World Superbike test seventh fastest.
His crew chief, Giulio Nava, said: “Sam is suffering from the after-effects of his crash in Valencia, but he put himself to the test anyway at Jerez to continue growing. We have a long season ahead of us, so for the moment it is important to rack up the miles in the saddle and get to know the mechanisms of the team.
“Despite his physical difficulties, I think these tests added another notch in the belt for Sam's apprenticeship. I'm sure that in Malaysia his potential will begin to show. We can't consider the times from these tests as any real indication.�
Espargaro clocked up a total of 80 laps as he adjusts to the Aprilia following his switch from the factory Suzuki.
“We are heading into the winter break with good sensations,� said Espargaro's crew chief, Marcus Eschenbacher.
“Aleix confirmed what he demonstrated in Valencia, both in terms of performance and harmony with the RS-GP. We have identified a rather precise technical direction to accommodate his riding style and during the winter we will work on bringing a further advanced bike to the first tests at Sepang.
“The weather did not help us and we also had a crash, but we can look forward to the 2017 season optimistically.�
